' To all whom it may concern:1

Beit known that I, ALBERT A. Arm, a resident of Brookfield, in the county of Cook and State of Illinois, have invented certain.

new and useful Improvements in Razor- Sharpeners, of which the ollowingis a full, clear, and exact description. 'Y

The invention relates to stropping-machnes for razors and designs to provide a m machine whereby. a large number of razors may be quickly stropped or sharpened.

`The inventionconsists in the several novel features hereinafter set forth and more particularly defined by claim at the conclusion hereof. L u

in the drawings: Figure 1 is a side eleraticn of a machine embcdyi the invention. Fig. 2 *is-a centralflongitudin'al section. Fig. B is la`plan of a portion of 'the The improved machine comprises a tableV 10 supported by legs 11 and upon this table are mounted a number of frames 12, each comprising a pair 4of sides `adapted'to carry mechanism for sharpening a razor and it will be understood that. any desired number 'of these frames and mechanisms may be provided -to increase the capacity of the machine. .A rockerfshaft 14l extends across the v'central portion of each frame 12 and is pro vided with a razor-clamp or holder. '15, which .ccnsistsof jaws 16, each of which is '85 secured to an arm 17 which has one of its ends secured in a recess 18 in the rockerfshat 14, by a screw 19. The outer ends of each jaw are extended laterally, and between them the razor will be clamped. The upper jaw-16 is provided with studs20,A ada ted -to` pass throughuholes usually forme in sasfetjf.-razors.` The clamp arms 17 are famed of spring metaland are adaptedjto be ressedto ther by a slidable member 2 1 46 which exten s through lslots 22 formed fin the members respectively, so that "as, said member isiushed'outwardly in the-slots,

jaws 20 w be forced together to firmly clamp the razor therebetween. This shaft '14., when rocked, #cause the clamp to swing from one side to `the .other to cause the strop to be 'applied' to the opposite sides of eaeh edgertion of the blade. Insharp- Irazors avingcutt-ing edges at `oppo- 5 `56 site sides, the blades may be reversed inthe machine. Fi 4 isa vertical `section taken` l clamp so both edges of the blade may be stropped.

A strop 24 is adapted lto be reciprocated and applied to the blades held in the holders. For the purpose of guiding the strop so` that the razor, when swungl vto one side of the rock-shaft 14 will have one side applied 'to thestrop and when swung to the 'opposite side, the opposite side o'f the same edge will be applied to the strop, a guide-roller 25 is mounted at one end of each frame and a guide-roller 26 at the opposite end. These rollers 25 and '26 are disposed to back up the strop where the razors are appliedto it and are mounted in bearings 27 onv the frames 12 and 13 respectively. For the purpose of guiding the strop away fromv the clamp and at a pro er angle with respect A\to the edge of the b ade,fa guide-roller 28, journal'edin 'frames 1 2v and 13, is disposed below each rock-shaft 14. Strop 24 extends progressively around the rollers 25, 28 and 26 of each strop'ping mechanism, so that the d-ierent portions of the stro will be simultaneousl drawn across fthe Jaws-.of thedifferent b ailes in the clamps, as shown in the drawings. One end of the strop 24 is secured, by a clamp 26', to one end of a rocking-lever 27 and the other end of the strop is secured, by a similar clamp 28', to the opposite ,end of said levenf, The latter is pivoted at its center upona shaft 29, which is mounted in bearings 30v secured to framemembers 31 below the table 10. The oscillation of the lever willcause thestro to be operated back 'and forth lacross the of the several blades held in the ho ders. Travel of thestrop in one direction causes it to be drawn angularlyacross one side of the edge ofthe blade and in order to strop the other side of the same edge, it is necessary that the clamplshould be Eswung'to the opposite side so that the edge-portion will be applied tothe strop. This oscillation of the rock-shafts 4, clamps 15 and the blades therein, is acted by a ben 33, whichy has each -of its ends' secured b a clam 34, tot. vlever 35 res actively, 'whgc ,is ar to stropfopera ing lever v2A and is pivot` mounted on the shaft -29. Each roclsh' l,

14 has secured to one of its vends. a pulley 35', which is rictionall.' operated ,by ebelt 33 and at each side 'oA pulley 35', the b'elt is guided by sheavesb', the belt be' trained around the several pulleys 35 a sheav 110 36 of the several stropping mechanisms, so tliat'all of the shafts 14 will be oscillated simultaneously in the same direction. Levers 2T and 35 for operating belt 33 and strop 24 respectively, are oscillated by a crank 3S on a driven-shaft 39 which is mounted in suitable bearings 40 and 41 on the frame below the table and may be driven by a pulley 42 which is adapted to be driven by an electric motor or manually. Crank 38 is operatively connected to levers 35 and 27 by a link 43 and a pin 44, which is connected to both of said levers.

In operation, assuming each of the holders 15 to have-a razor therein and power to be applied to the crank-shaft 39 and further assuming the parts to be in`the position shown in Figs. 1 and 2, crank 38 will lift the left hand ends of the levers 27 and 35. The initial movement of lever 35 will operate belt 33, which, by reason of its engagement with each of the rollers 35 on rock-shafts 14, will immediately operate said shafts to swing the razors to the opposite sides of the rock-shafts, so that one side of the edgeportion of each blade will be applied to the strop adjacent rollers 26, the strop being drawn angularly across the edge and outwardly from the razor. After the razors have been brought into engaging relation with the strop, belt 33 will slip over pulleys 35, the frictional engagement serving to hold the blades in contact with the strop. The travel of the strop will continue in the same direction until levers 27 and 35 travel in the opposite direction and the initial movement in such direction will immediately cause-belt 33 to rbck shafts 14 and reversely apply the razors. In practice, the belt 33 is trained rather tightly around pulleys 35 and shafts 36, so as to cause the rock-shaftsv 14 and the clamps to immediately respond to the reverse movement of lever 35, While the strop is not so tightly drawn between the ends of lever 27 and therefore the razors will be shifted out of contact with the strop before reverse movement of the latter commences.

Each lframe 12 constitutes a support for all of the devices for manipulating one razor and guiding the strop for such razor and any number of these devices may be added to give the machine the desired capacity. Furthermore, it is not necessary to stop the machine to change the blades in the holders because the operator can catch any of the holders as they are moving from one side of their rock-shafts to the other and hold such holder in an upright position, the belt 33 slipping over its roller 35 and while the clamp is so held, the razor may be removed or may be turned around to bring its other cutting edge into position to bestropped.

since these may be modified within the scope of the appended claims, Without departing from the spirit and scope of the invention.
